General Information

Valve systemLoad sensing proportional valve type PVG 120 is a combined directional and flow control valve which is supplied as a valve group consisting of modules specified to match particular customer needs. The flexible nature of this valve will allow an existing valve bank to be easily adapted to suit changes in requirements.

General characteristics• Load-independent flow control:

– Oil flow to an individual function is independent of the load of this function – Oil flow to one function is independent of the load pressure of other functions

• Good regulation characteristics• Central pilot supply built in when the valves are actuated electrohydraulically• Energy-saving• Up to eight basic modules per valve group

Pump side module – PVP• Built-in pressure relief valve• System pressure up to 400 bar [5800 psi]• Pressure gauge connection• Versions:

– Open centre version for systems with fixed displacement pumps – Open centre version prepared for an extra relief module – Closed centre version for systems with variable displacement pumps – Closed centre version without system pressure relief valve for variable displace

ment pumps with built-in pressure relief valve.

Basic module – PVB• Integrated pressure compensator in channel P• Interchangeable spools• Depending on requirements the basic module can be supplied with:

– Shock/suction valves – Adjustable LS pressure limiting valve for ports A and B – LS connection – Module for oil flows exceeding 180 l/min [47.6 gpm] – Different spool variants

Actuation modulesThe basic module is always fitted with mechanical actuation PVM, which can be combined with the following as required:• Electrical actuation

PVG 120 with Open Centre PVP

PVG 120 with Closed Centre PVP

Function

When the pump is started and the main spools (1) in the individual basic modules are in neutral position, oil flows from the pump, through connection P, across the pressure adjustment spool (2) to tank.The oil flow led across the pressure adjustment spool determines the pump pressure (stand-by pressure). If a reduced stand-by pressure is required, an extra relief valve PVPH or PVPE can be used in PVP (see characteristics for neutral flow pressure, page 25).

When the main spools are actuated the highest load pressure is distributed across the shuttle valve circuit (3) to the spring chamber behind the pressure adjustment spool (2) and completely or partly closes the connection to tank.

The pump pressure is applied to the right-hand side of the pressure adjustment spool (2). The pressure relief valve (4) opens when the load pressure exceeds the set value, allowing pump flow to be diverted back to tank.

In the basic module the compensator (5) maintains a constant pressure drop across the main spool – both when the load changes and when a module with a higher load pressure is activated.

Shock and suction valves with a fixed setting (7) and the suction valves (8) on ports A and B are used to protect individual working functions against overload.

In the basic module it is possible to build in an adjustable LS pressure relief valve (6) to limit the pressure from each working function. The LS pressure limiting valve saves energy:• Without LS pressure limiting valve all the oil flow to the working function will be led

across the combined shock and suction valves to tank if the pressure exceeds the fixed setting of the valves.

• With LS pressure limiting valve an oil flow of only about 2 l/min [0.5 US gal/min] will be led across the LS pressure limiting valve to tank if the pressure exceeds the valve setting.

In the closed centre version an orifice (9) has been fitted instead of the plug. This means that the pressure adjustment spool (2) will only open to tank when the pressure in channel P exceeds the pressure relief valve setting (4).

In load sensing systems the load pressure is led to the pump regulator via the LS connec-tion (10). So the orifices (11) have been removed, and a plug (12) has been fitted instead of one of the orifices.

In neutral position the pump regulator will set the displacement so that leakage in the system is just compensated for.

When a main spool is activated, the pump regulator will adjust the displacement so that the set differential pressure between P and LS is maintained.

The pressure relief valve (4) in PVP is set for a pressure of about 30 bar [435 psi] above maximum system pressure (set at the pump or an external pressure relief valve).If the system or the pump regulation has a pressure relief valve, it is possible to use a PVPV pump side module, without integrated pressure adjustment spool and pressure relief valve.

PVEH adjusts the main spool position so that it corresponds to an electrical control signal – for example from a remote control unit.

The control signal (set-point signal) is converted into a hydraulic pressure which moves the main spool. The position of the main spool is converted in the positional transducer (C) to an electric signal (feed-back signal). This signal is registered by the electronics.

The variation between the set-point signal and feed-back signal actuates the solenoid valves. Thus the hydraulic pressure moves the main spool into the correct position.

Special features of PVEH:• Inductive transducer• Integrated pulse width modulation• Low hysteresis• Fast reaction time• Hirschmann or AMP connector• Fault monitoring with transistor output for signal source• Low electrical power• No set-up procedure

14 520L0356 • Rev IC • Jul 2012


LVDT, Inductive transducer (Linear Variable Differential Transformer)When the main spool is moved a voltage is induced proportional to the spool position. The use of LVDT gives contact-free (proximity) registration of the main spool position. This means an extra-long working life and no limitation as regards the type of hydraulic fluid used. In addition, LVDT gives a precise position signal of high resolution.

Integrated pulse width modulationPositioning of the main spool in PVEH is based on the pulse width modulation principle. As soon as the main spool reaches the required position, modulation stops and the spool is locked in position.

A fault monitoring system is provided in all PVEA, PVEH and PVES modules. The system is available in two versions: • The active fault monitoring type, which provides a warning signal, deactivates the

solenoid valves and drives the spool in neutral. • The passive fault monitoring type, which provides a warning signal only. Both active and passive fault monitoring systems are triggered by three main events:

1. Input signal monitoringThe input signal voltage is continuously monitored. The permissible range is between 15% and 85% of the supply voltage. Outside this range the section will switch into an active error state. 2. Transducer supervisionIf one of the wires to the LVDT sensor is broken or short-circuited, the section will switch into an active error state.

3. Supervision of the closed loopThe actual position must always correspond to the demanded position (input signal). If the actual spool position is further than the demanded spool position (>12%, PVEA: >25%), the system detects an error and will switch into an active error state. On the other hand, a situation where the actual position is closer to neutral than that demanded will not cause an error state. This situation is considered “in control”.When an active error state occurs, the fault monitoring logic will be triggered:

Active fault monitoring• A delay of 500 ms (PVEA: 750 ms) before anything happens.• The solenoid valve bridge will be disabled and all solenoid valves will be released.• An alarm signal is sent out through the appropriate pin connection.• This state is memorized and continues until the system is actively reset (by turning off

the supply voltage).

Passive fault monitoring • A delay of 250 ms (PVEA: 750 ms) before anything happens. • The solenoid valve bridge will not be disabled but still control the main spool position.• An alarm signal is sent out through the appropriate pin connection.• This state is not memorized. When the erroneous state disappears, the alarm signal

will turn to passive again. However, the signal will always be active for a minimum of 100 ms when triggered.

15520L0356 • Rev IC • Jul 2012


To prevent the electronics from going into an undefined state, a general supervision of the power supply and the internal clock frequency is made. This function applies to PVEH - and will not activate fault monitoring:

1. High supply voltageThe solenoid valves are disabled when the supply voltage exceeds 36 V, and the main spool will return/stay in neutral.

2. Low supply voltageThe solenoid valves are disabled when the supply voltage falls below 8.5 V, and the main spool will return/stay in neutral.

3. Internal clockThe solenoid valves are disabled when the internal clock frequency fails, and the main spool will return/stay in neutral.

WWarningIt’s up to the customer to decide on the required degree of safety for the system.

Different degrees of safety are described on pages 34 to 37. The fault monitoring does not work if the supply voltage to PVEH is cut off - for example by a neutral position switch. When using PVEH with passive fault monitoring it is up to the customer to decide on the degree of safety required for the system (see page 34).

PVG 120 Proportional ValveTechnical InformationSafety in Application

Building in Safety All makes and all types of control valves (incl. proportional valves) can fail. Thus the necessary protection against the serious consequences of function failure should always be built into the system. For each application an assessment should be made for the consequences of pressure failure and uncontrolled or blocked movements.

To determine the degree of protection that is required to be built into the application, system tools such an FMEA (Failure Mode and Effect Analysis) and Hazard and Risk Analysis can be used.

FMEA (Failure Mode and Effect Analysis) IEC EN 61508FMEA is a tool used for analyzing potential risks. This analytical technique is utilized to define, identify, and prioritize the elimination or reduction of known and/or potential failures from a given system before it is released for production.Please refer to IEC FMEA Standard 61508.

Hazard and Risk Analysis ISO 12100-1 / 14121This analysis is a tool used in new applications as it will indicate whether there are special safety considerations to be meet according to the machine directives EN 13849. Dependent on the determined levels conformety this analysis will detirmine if any extra requirements for the product design, development process, production process or maintenance, i.e. the complete product life cycle.

WWarningAll makes/brands and types of directional control valves – inclusive proportional valves – can fail and cause serious damage. It is therefore important to analyze all aspects of the application. Because the proportional valves are used in many different operation conditions and applications, the manufacturer of the application is alone responsible for making the final selection of the products – and assuring that all performance, safety and warning requirements of the application are met. The process of choosing the control system – and safety levels – is governed by the machine directives EN 13849 (Safety related requirements for control systems).

Oil

Particle Content, Degree of Contamination


The main duty of the oil in a hydraulic system is to transfer energy; but it must also lubricate the moving parts in hydraulic components, protect them against corrosion, and transport dirt particles and heat out of the system. It is therefore important to choose the correct oil with the correct additives. This gives problem-free operation and long working life.

Mineral oilFor systems with PVG 120 valves Sauer-Danfoss recommends the use of mineral-based hydraulic oil containing additives: Type H-LP (DIN 51524) or HM (ISO 6743/4).

Non-flammable fluidsPhosphate-esters (HFDR fluids) can be used without special precautions. However, dynamic seals must be replaced with FPM (Viton) seals. Please contact the Sauer-Danfoss Sales Organisation if the PVG 120 valve is to be used with phosphate-esters.The following fluids should only be used according to agreement with the Sales Organisation for Sauer-Danfoss:• Water-glycol mixtures (HFC fluids)• Water-oil emulsions (HFB fluids)• Oil-water emulsions (HFAE fluids)

Biodegradable oilsPVG 120 valves can be used in systems using rape-seed oil. The use of rape-seed oil is conditional on• it complying with the demands on viscosity, temperature and filtration etc.

(see chapters below and technical data page 10).• the operating conditions being adapted to the recommendations of the oil supplier.

Before using other biodegradable fluids, please consult the Sauer-Danfoss Sales Organisation.

Oil filtration must prevent the particle content from exceeding an acceptable level, i.e. an acceptable degree of contamination.Maximum contamination for PVG 120 is 23/19/16 (see ISO 4406). Calibration in accordance with the ACFTD method.

In our experience a degree of contamination of 23/19/16 can be maintained by using a filter fineness as described in the next section.

39520L0356 • Rev IC • Jul 2012


Filtering

Conversion Factors


Effective filtration is the most important precondition in ensuring that a hydraulic system performs reliably and has a long working life. Filter manufacturers issue instructions and recommendations. It is advisable to follow them.

System filtersWhere demands for safety and reliability are very high a pressure filter with bypass and indicator is recommended. Experience shows that a 10 µm nominal filter (or finer) or a 20 µm absolute filter (or finer) is suitable.It is our experience that a return filter is adequate in a purely mechanically operated valve system.

The fineness of a pressure filter must be selected as described by the filter manufacturer so that a particle level of 23/19/16 is not exceeded. See “Particle content, degree of contami-nation”. The filter must be fitted with pressure gauge or dirt indicator to make it possible to check the condition of the filter.

In systems with differential cylinders or accumulators the return filter must be sized to suit the max. return oil flow. Pressure filters must be fitted to suit max. pump oil flow.

Internal filtersThe filters built into PVG 120 are not intended to filter the system but to protect important components against large particles.Such particles can appear in the system as a result of pump damage, hose fracture, use of quick-couplings, filter damage, starting up, contamination, etc.

The filter that protects the pilot supply in the tank side module has a mesh of 125 µm. It is obtainable as a spare part and is easy to replace.

The filter protecting the essential PVE parts has a mesh of 125 µm.
